　　to put one’s foot in one’s mouth

　　Definition: to say the wrong thing in a certain situation and become very embarrassed

　　【世博精解】

　　如果你把脚放在了嘴里，那一定是个可笑尴尬的场面吧。”put your foot in your mouth”这个惯用语的意思就是说你在某个场合说错了话，搞的自己或别人很尴尬。这主要是美英的说法，还可以说成“to put one’s foot in it”,是一样的意思.例如I really put my foot in it/ in my mouth with Julie. I didn’t realize she was a vegetarian.从这句话来看，“我”肯定时说了诸如“help yourself to some steak, it’s really well cooked”这样的话，弄的场面很尴尬。其他例子如：Let's all be very careful what we say at the meeting tomorrow. I don't want anyone putting their foot in their mouth.注意这里的foot还是用单数。

　　Example dialog :

　　A: I am so embarrassed; I had no idea he could hear me in the next room when I was talking about his wife!

　　真是尴尬死了，我根本不知道他在隔壁房里能听到我在谈论他的妻子！

　　B: Ouch! Sounds like you really put your foot in your mouth!

　　啊呀！听起来你真的是说错话了！
